Triggers

Like most organizations you are obligated to know who is onsite so you can account for them in an emergency. You may also want to know if a person comes into your building after normal business hours, or if they are onsite alone, or if they are expected to depart at 9pm but did not, or how many people are onsite after 6pm and much more...
One of the benefits of WhosOnLocation is the way you can set up various business rules to automate notifications and alerts and make sure that nothing falls through the cracks. Triggers is the tool that you use to make all of this automation happen.
